Really like this idea, and nice topic.
I think with silent upgrades to products where the mfg claim a noticeable improvement in sound quality for changes to an active product, such as antipodes, despite the same product name, I think that really deserves a different name. Either something like product v2, r2, g2, whatever you want to call it, something to differentiate the new upgrade so people actually know. Really with them they’ve embraced this now, but in the past it was really confusing figuring out what k50 I had, what changes they were making, and why the price increases (and they’re not the only ones who do this of course). I also think in those circumstances, mfg should offer the ability for customers who bought the older version of the product (from an authorized dealer or seller) within a specific timeframe the new one is released, like a few months perhaps, to get a free upgrade with them only paying cost of shipping. I do think there should be limits to that though but for the most part I think that would be a fair way to handle it, although I understand why some mfg can’t really afford to do that.
I understand that revisions can sometimes be unintentionally better (or worse) simply because of parts swaps and shortages, like if a mfg has to substitute a different transformer or caps, or perhaps has to use a bit different mfg techniques, or some other change that isn’t intended to really improve/upgrade the product and is more intended to be able to continue production. In those cases, I think it’s mostly fine if it’s not explicitly stated, but only as long as the mfg feels that it’s not a noticeably different product from their last. Of course this will absolutely cause some level of shift within the community surrounding the products going nuts over the revisions, but I think if the mfg aren’t making the changes to really change the sound, it’s fine if they don’t really note the changes outright
Personally for myself I only really care about anything that chances sonically rather than anything aesthetic or looks wise, but that’s just a me thing and I’m sure some people care about looks lol.
It is always weird to me to see some products basically being pretty noticeably changed or upgraded with the price point shifted up under the exact same name, sometimes not even having a solid way to identify different revisions. I don’t really think a lot of mfg do this stuff maliciously, either doing it out of necessary or for the sake of bettering their product, but really the problem just comes in how they’re labeled, marketed, and introduced. If the people making it feel like it’s an improvement over the old, I’d prefer they mark that in some easy to see way. If they don’t feel like it impacts much at all, I’m fine with it not really being directly marked as something different. I don’t want to see a million different versions simply because there’s something slightly different about the design, but I also don’t want to see noticeably different designed and sounding products under the same name without any clear indication that things have changed
